Asheron's Cache Bug

Very annoying bug today. Unlocked and opened the Asheron's Cache in Warden's Hideout when another fellowship member clicked on the cache as well.

All I saw was question marks instead of items and I could not collect any of them. Waited several minutes and still no change.

Needless to say once I clicked off the cache it closed and re-locked.

So me..out my only sigil and and no moonstone.
